2. ABOUT THIS MANUAL
This manual describes the use of a MC12 and a MC12P.
As the 2 models differ slightly, a few sections in this manual are divided into model specific
descriptions. Unless otherwise stated the word MC12 covers both models.
3. MC12 SYSTEM DESIGN
MC12 is the main computer of the Flexicon Multi Filling System (FMFS). MC12 can not
perform filling by itself, but is developed for controlling one of Flexicons pumps for example
PD12 or PD22 series.
The MC12 uses an RS485 multidrop network to communicate with the connected drives.
The drives may also be controlled from a PC; in that case the PC communicates through an
RS485 multidrop network as specified in the Flexicon protocol.
3.1 RS485 multidrop network
Up to 16 drives may be connected to the Flexicon network. The maximum length of the
network is 500 meters.
Figure 1 – Drive Connections
The network is physically connected through special Flexicon communication cables marked
"type 3". The MC12 is connected via a cable 3 to the first drive of the system, and
subsequently the individual drives are inter-connected with a cable 3. The last drive is
provided with a terminator which terminates the network.
It is important that each drive is allocated an individual address in order that the MC12 can
identify individual drives.
Address 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
SW1 1 010101010101010

SW3 1 111000011110000
SW4 1 111111100000000
Figure 2 – Switch address

Operators and Reference Manual
MC12
MC12 OM RM EN 74-111-132 v1.03.doc Ver. 1.03 Page 7 of 47
The address is changed by setting a dip-switch positioned on the bottom of the drive. This
switch must only be activated when the drive is turned off at the main isolator.Addresses
from 1 to 16 may be selected, and Fig. 2 shows the different combinations.
When the MC12 is started, the whole network is initialised. The MC12 makes a global
enquiry on the network and receives feedback from the individual drives, allowing it to record
how many and which types of drives are available on the network.
When the drives have started their filling operations with their respective parameters, the
MC12 will continuously scan the network to record when the drives have completed their
tasks.
Finally all the counters are updated and the next job instruction (if any) is transmitted.

6.3 Parameters
In the following a parameter will be a single value like for example volume, velocity, number
of fillings etc.
6.4 Programs
In the following a program will be a complete set of parameters which together form a
program according to which MC12 and the connected pump will operate.
6.5 General information on the programming of MC12
MC12 is equipped with a battery in the memory and will therefore always remember the
programmed parameters, even if the main switch is turned off.
The programming is made via functions, i.e. every operating parameter has its own function
number.
The programming is made by entering the function number followed by "ENT".
This will make the required function appear in the prompt line of the display and show the
current value or information of the function.
This value will automatically be overwritten when entering the new value. After being entered,
the new value will be displayed in the prompt line. The new value is entered into the
computer by pressing "ENT".
The new value will be displayed in the status lines at once.
Example:
If a volume of 8.5 ml is required, the following should be entered:
<1>+<ENT>+<8>+<.>+<5>+<ENT>
MC12 knows automatically which filler is connected. Consequently, values which are not
valid for this pump will not be accepted.
If a faulty value is entered, it will not be entered, and a "beep" sound will be heard.

6.7 Description of functions
The individual functions will be described in the following:
6.7.1. Function 1 -Volume
Value: Choice of ml and grams as unit.
Function 1 informs the system of the volume to be filled.
Value
Option
Related Function(s)
Min
Max
0.01
9999.9
ml. or gram
72
The entered value must be between 0.01 and 9999.9. If a value outside these limits is
entered, the MC12 will correct the value to the nearest value within the limits and ask for
acceptance via <ENT>.
When a volume is entered, the system will calculate the new parameter value which will then
be used from the start of the next fill.At the same time, the status line will be updated.
For an individual fill only the parameter value for the drive in question will be changed.
For parallel or serial filling, the volume should be entered in drive 0 and the parameter value
will be calculated for all connected drives.
6.7.2. Function 2 - Tube diameter
Value: Inside diameter of the tube in mm.
Drive type Tube inside diameter in mm
PD12P 0.5 0.8 1.2 1.6 3.2 4.8 6.0 8.0
Enter the tube diameter used. The MC12 will only accept original Flexicon tube diameters.
The diameters are specified in the manual for the drive and can be read on the tube gauge
supplied with the drive.
As most of Flexicons drives are of the peristaltic type and work with tubes, the system must
know the current tube diameter.
When programming a drive that does not use tubes as pumping element, this function will
not be activated.
The tubes should be indicated by their inside diameter and from these data the MC12 will
calculate how many revolutions the selected pump head should make in order to dispense
the required volume.
If an unrecognised tube diameter is entered for the selected drive, the MC12 will not accept
this diameter but will instead ask for a tube diameter from the original Flexicon range.

Operators and Reference Manual
MC12
MC12 OM RM EN 74-111-132 v1.03.doc Ver. 1.03 Page 14 of 47
6.7.3. Function 3 - Velocity
Value: Revolutions per minute (rpm).
Enter the required velocity.
Velocity range depends on tube size applied.
Range:
Tube Sizes
Max. Velocity
Max. acceleration
0.5 - 0.8 – 1.2 – 1.6
600
200
3.2
500
150
4.8 - 6.0 – 8.0
400
100
If a value outside the range is entered, the MC12 will automatically correct the value to the
closest value allowed and the operator has to accept it by pressing the <ENT> key.
The fastest filling will be carried out at the highest velocity setting but the velocity should
always be adjusted to suit the characteristics of the product and to reduce splashing or
foaming.
If the velocity is changed during a fill, the fill will be completed using the original parameters
and the new value will not be applied until the start of the next fill.
If the velocity is changed while using the unit as a pump, the drive will apply the new
parameters immediately. The change will be carried out at the acceleration or deceleration
entered in Function 4.
6.7.4. Function 4 - Acceleration/deceleration
Value: An integral number.
The filling can start and stop more or less abruptly.
This function offers a choice of values between 1 and 200 dependent on the tube size and
drive; 1 = slowest, 200 = fastest.
Tube Sizes
Max. Velocity
Max. acceleration
0.5 - 0.8 – 1.2 – 1.6
600
200
3.2

400
100
If a value outside the range is entered, the MC12 will automatically correct the value to the
closest value allowed and the operator has to accept it by pressing the <ENT> key.
The function is used for optimizing the filling according to the product and the shape of the
bottle.
Function 4 affects pumping as well as filling and calibration.
If the value of the parameter is changed during a fill or calibration, the new value will not be
applied until the start of the next fill or calibration.

MC12 OM RM EN 74-111-132 v1.03.doc Ver. 1.03 Page 15 of 47
6.7.5. Function 5 - Reversing (back suction)
Value: An integral number.
When the filling stops, the filler can be asked to produce a small back suction to prevent
dripping.
The back suction can be set at values between 0 and 10.
0 = no back suction
10 = maximum back suction.
The value has no relation to any other parameters and is solely a number of degrees of a
rotor turn. Consequently, the volume that is sucked back will depend on the tube diameter.
If a value outside the range between 0 and 10 is entered, the MC12 will automatically correct
the value to the closest value allowed and the operator has to accept it by pressing the
<ENT> key.
If the value of the parameter is changed during a fill, the new value will not be applied until
the start of the next fill.
6.7.6. Function 6 - Batch size
Value: Number.
Enter the number of fillings you want the filler to perform when started by <GO>, foot switch
or via electrical signal.
There is a choice between 1 and 65,000.
When the filler is operating in an automatic system, where the system itself starts the filler
each time a bottle is in position, the value in this function must always be 1.
If a value outside the range between 1 and 65,000 is entered, the MC12 will automatically
correct the value to the closest value allowed and the operator has to accept it by pressing
the <ENT> key.
The value in Function 6 will only be active during filling, and after each fill the drive will wait
for the time delay specified in Function 7 before the next fill is started.
When the system has completed the number of fills entered in Function 6, the system will
stop and wait for a new <GO> command or a new starting signal, after which the system will
once again carry out the number of fills entered in Function 6.
For filling in individual mode, the batch size should be entered for each single drive. For fills
in parallel or serial mode, the batch size should be entered in drive 0.

MC12 OM RM EN 74-111-132 v1.03.doc Ver. 1.03 Page 16 of 47
6.7.7. Function 7 - Delay
Value: Seconds.
If more than one fill is selected in Function 6, enter the required delay between the fills.
The value of the delay can range between 0.0 and 25.5 seconds, with intervals of 0.1
second.
Function 7 is only active while filling is carried out and only if more than one fill has been
entered in Function 6.
6.7.8. Function 8 - Completed fills
Value: Number.
Nothing can be entered in this function, as it only displays the number of fills completed since
the latest reset of the function.
To reset this function, press the <C> key.
6.7.9. Function 9 - Specific gravity
If the product has another specific gravity than the usual 1.0 (Water), then it is entered here.
The default value is 1.0000 g/ml.
Changing specific gravity should be followed by a calibration .
6.7.10. Function 10 - Output rate
Value: Number of fills per time unit.
Nothing can be entered in this function as it only displays how many fills the system carries
out per time unit.
The time unit can be changed between hours and minutes in Function 70. See also
information about Function 70.
The function operates as follows: The MC12 records the precise time between two fills via
the built-in clock, and calculates the number of fillings per time unit.
The display is updated at the completion of each fill.
The function can be called up for viewing, but it cannot be reset and values cannot be
entered in this function.

6.7.11. Function 11 - Accumulated volume
Value: Litre
Nothing can be entered in this function, as it only displays the total volume used since the
latest reset of the function.
To reset this function, press the <C> key.
The value of this function is updated at the completion of each fill.
If the value of accumulated volume is less than 1,000 litres, it will be displayed with 3
decimals. If the value is equal to or more than 1,000 litres, it will be displayed with one
decimal.
6.7.12. Function 12 - Maximum flow
Value: Volume per time unit.
Nothing can be entered in this function as it only displays the current maximum flow.
The read-out is based on the flow created when the rotor runs at the required velocity.
The function reads out how much liquid the system pumps through the tubes per time unit.
This unit can be changed in Function 71. See the information about Function 71.
The read-out will be updated immediately after changing the value in Function 2 or Function
3.
6.7.13. Function 16 - Pumping direction
Value: Clockwise or counter-clockwise.
As not all drives can work with more than one pumping direction, this function will only be
active when connected to a drive with that option e.g. GD30I.
Start by entering: <1>+<6>+<ENT> and display shows: “DIRECTION (1/2):”
1 = CLOCKWISE ROTATION = product from top of pump
2 = COUNTER-CLOCKWISE ROTATION = product from side of pump
Thick creams require a feed hopper mounted on top of the pump and consequently, pumping
direction 1 is used.
For products which flow more freely and can be drawn up against gravity e.g. shampoo, the
suction tube is mounted on the side of the pump and consequently, pumping direction 2 is
used.
Select the wanted value and press <ENT>

6.7.14. Function 17 - Timer 1
Value: Seconds.
A time interval can be set between a starting signal and the time the drive actually starts.
The starting signal can be either the <GO> key or an external starting signal.
The range is between 0.0 and 25.0 seconds at intervals of 0.1 second.
If a value outside the range 0.0 to 25.0 is entered, the MC12 will automatically correct the
value to the closest value allowed and prompt the operator to accept it by pressing <ENT>.
For instance if 1.25 sec. have been entered, the MC12 will round the value to 1.2 sec.
6.7.15. Function 18 - Timer 2
Value: Seconds.
A delay can be set between the starting signal and the time the drive actually starts. The
starting signal can be either the <GO> key or an external starting signal.
The range is between 0.0 and 25.0 seconds at intervals of 0.1 second.
For the duration of the delay specified in Timer 2, the status signals of the two external ports
will be active and continue to be active during the filling of the drive.
If a value outside the range 0.0 to 25.0 is entered, the MC12 will automatically correct the
value to the closest value allowed and prompt the operator to accept it by pressing <ENT>.
For instance if 1.25 sec. have been entered, the MC12 will round the value to 1.2 sec.
6.7.16. Function 19 - Timer 3
Value: Seconds.
A time interval can be set where the status signal says that the filler is operatingAFTER it
actually stopped.
The interval is from 0.0 to 25.5 seconds.
For the duration of the delay specified in Timer 3, the status signals of the two external ports
will be active after the completion of the filling of the drive.
If a value outside the range between 0.0 and 25.5 is entered, the MC12 will automatically
correct the value to the closest value allowed and the operator has to accept it by pressing
the <ENT> key.
For instance if 1.25 sec. have been entered, the MC12 will round down the value to 1.2 sec.

6.7.17. Function 20- Operator number
Value: digits
An operator number can be entered in Function 20.
The maximum number of digits in an operator number is 12. This means that an operator
number is an integral number between 0 and 999999999999.
With this function it is possible to inform the system which operator is in charge of the current
production. The operator number entered will always appear on print-outs of the log (F24)
and the operating parameters (F29).
6.7.18. Function 21 - Batch number
Value: digits
A batch number can be entered in this function.
The maximum number of digits in a batch number is 12. This means that a batch number is
an integral number between 0 and 999999999999.
With this function the operator can inform the system of the batch or production number
under which the current production is recorded. The batch number entered will always be
shown on print-outs of the log (F24) and print-outs of the operating parameters (F29).
6.7.19. Function 22 - Start Log
By using this function automatic logging in the internal memory can be started. When the log
is started all parameters as well as changes and calibrations will be entered and may
subsequently be printed out for full production documentation.
Start log by entering: <2>+<2>+<ENT>
When the function is started, the MC12 will ask for confirmation that the log start should go
ahead by prompting the user to enter (Y) for 'yes' and (N) for 'no'. If <N> for 'no' is pressed,
the MC12 will exit the function.
If <Y> for 'yes' is pressed, the following question will appear:
F22 DEL OLD LOG (Y/N):
If <N> for 'No' is pressed, all existing information will be saved in the memory and the new
data will be stored after the original data. Please note that the log capacity is limited;
therefore an old log should always be deleted WHEN it has been printed out.
If <Y> for Yes is pressed, all old data in the memory will be deleted before the log is started.
As long as the log is active, an L will be visible at the right hand side of the prompt line.

6.7.20. Function 23 - Stop Log
This function stops the automatic logging of production data (Log).
When a production has been completed and the log has been active, the log should be
stopped before print-out.
If the log is active, an L will be visible at the right side of the prompt line.
Stop log by entering: <2>+<3>+<ENT>
When the function is entered, the MC12 will ask for confirmation that the log should stop by
prompting the user to enter (Y) for 'yes' and a (N) for 'no'. If <N> for 'no' is pressed, the MC12
will exit the function.
If <Y> for yes is pressed, the logging of data for the memory will be stopped.
6.7.21. Function 24 - Print Log
If a printer is connected, this function will start the printing of the log.
When the function is started, the MC12 will ask for confirmation that the log should be
printed by prompting the user to enter (Y) for 'yes' and (N) for 'no'.
If <N> for 'no' is pressed, the MC12 will exit the function.
If <Y> for 'yes' is pressed, the MC12 will prompt for Y/N decision regarding continuous log.
If <Y> for ‘yes’ is pressed, the incoming log will be printed out continuously. These log-data
will automatically be erased. This function can be used if MC12 is used together with a scale
and if there is a risk of overloading the log by generating many data.
If <N> is pressed, the complete log will be printed out and printer will stop at the end of log.
The printing is carried out as background printing, i.e. the MC12 can be operated while
printing takes place.
Stop the log stopped with function 23, and MC12 prints out the number of fillings and
accumulated volume recalibrations from balance as well as related average and standard
deviation for recalibration values.
If the MC12 is used with a balance (see function 49), the registered data from balance are
printed out as a part of log and the number.
Please be aware that specific gravity is printed only if the volume format is set to ml.
